Example of laser output control
One of the possible applications of polynomial definition is the laser output control.
Laser output control means:
Influencing the analog output in dependence on, for example, the path velocity.
$AC_FCTLL[1]=0.2
$AC_FCTUL[1]=0.5
$AC_FCT0[1]=0.35
$AC_FCT1[1]=1.5EX-5
STOPRE
ID=1 DO $AC_FCTUL[1]=$A_INA[2]*0.1 +0.35
ID=2 DO SYNFCT(1,$A_OUTA[1],$AC_VACTW)
;Depending on the path velocity (stored in $AC_VACTW) the laser output control
;is controlled via analog output 1
Note
The polynomial defined above is used with SYNFCT.
